I have each movie in a folder with the same name as the movie. Inside there I have a NFO file with the URL in it. It imports it everytime....
ONE exception though, if the URL does not have www in it then it will not import it.
so if you have this URL it will find it
http://www.imdb.com/title/tt0816462/
but if you have this URL it won't
http://imdb.com/title/tt0816462/
Even though that is a valid URL
Some groups are doing that now and I have to add the WWW to make them import
